Multi Resonant Stacked Micro Strip Patch Antenna Designs for IMT, WLAN & WiMAX Applications

Provided by: International Journal of Advanced Research in Computer Engineering & Technology Topic: Networking Format: PDF
In this paper, stacked multi resonant slotted Micro strip Patch Antennas (MPA) have been proposed which are suitable to be used for GSM, WLAN standard and WiMAX applications. The antennas have been designed using substrate of FR4 material. In the designed antennas, substrates having different thickness have been used. The performance of designed antenna has been observed by comparing without air gap between the stacks with same antenna having air gap of 0.8 mm between two stacks. It has been observed that air gap in stacking results in increase of antenna impedance bandwidth.
